Attempting a new installation of Ubuntu 12.04 LTS on what was a dual boot Windows 7 and Ubuntu 12.04 LTS laptop ( Sony intel i3 core 64 bit with 500GB HDD). I followed the following procedure
Install Ubuntu
• has at least 4.4 GB available, is connected to the internet, download updates while installing and install this third-party are all ticked this time
• I chose the Erase disk and install Ubuntu option ( since I want to have only Ubuntu 12.04 LTS operating system in my disk)
Now shows
The entire disk will be used
• 501GB free disk

I clicked the install now button. All data copied to the hard drive ( it was copied OK), askes for location, keyboared layout, and who are you. Started to install the Ubuntu 12.04 operating system. After some minutes, I got a report
Installation failed, the installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again.
So, Please give me simple advice on how to proceed.
Thank you

Try to use another installer source (USB Stick, CD, DVD) and reinstall system.
Also you can try to install Ubuntu 12.10 distribution. Sincerely for me, ubuntu 12.10 is more stable than Ubuntu 12.04 even if is not LTS.
